Optimize Your Images for Prezi Next

We all know how important visuals are for your presentations. Nothing shows off great visuals better than Prezi. But image files take up a lot of storage space and that can affect your prezi. Using the wrong kind of images can make your Prezi zoom transitions jerky. They also slow down the load time. There are three steps you can take to optimize your images so your Prezi Next presentations load faster and have nice smooth transitions.

Best file types for Prezi Next

In general, PNG is the best file type to use for Prezi Next. PNG, however, is a raster image type, so it’ll pixilate if you zoom too closely. Use a PDF file if you plan to use an extreme zoom. PDFs are vector images so they won’t pixilate. Prezi Next supports transparency in both PNG and PDF files.  When you insert a PDF file, Prezi will automatically make its white background disappear like magic. JPG and non-animated GIF images are also supported, but PNGs are smaller and render more quickly.

Best file size for Prezi Next

When Prezi loads your project for viewing, large images are resized to a width of 1800 pixels. Resizing takes time and resources. For the best and quickest load time, resize your images before inserting them into Prezi. Keep your image sizes down as much as possible. If the image doesn’t fill the entire screen, there is no need for it to be 1800 pixels wide. Use smaller images at a lower resolution if possible.

A background image is the most important image in your prezi. It fills the screen completely and is seen behind all your topics and subtopics. Background images don’t get compressed into 1800 pixels wide. The ideal dimensions for a background image is 2000 by 1125 pixels.

Tips for best results

One big image looks smaller to Prezi than several little ones. If your visual is a combination of several image files, merge them together into a single file before inserting it into Prezi. You don’t have to use a graphics program to do this. Just place them into PowerPoint, group them together, right-click and choose Save as Picture.

Here’s one last tip for you. When using an image multiple times in the same prezi, insert it only once, then copy and paste it. That way, Prezi only has to render it once instead of treating it like several different images.
